Director Independence

Our board of directors has undertaken a review of the independence of each director. Based on information provided by each director concerning his background, employment and affiliations, our board of directors has determined that Messrs. Coughlin, Ruffolo, Gibbs, Lu and Hamilton do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is “independent” as that term is defined under the listing standards of The Nasdaq Capital Market. In making these determinations, our board of directors considered the current and prior relationships that each non-employee director has with our company and all other facts and circumstances our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director, and the transactions involving them described in the section titled “Certain Relationships and Related Person Transactions.”

Board Committees

Our board of directors has established an audit committee, a compensation committee, and a corporate governance/nominating committee, each of which operates under a charter that has been approved by our board of directors.

Our board of directors has determined that all of the members of the audit committee, the compensation committee and the nominating and corporate governance committee are independent as defined under the applicable rules of The Nasdaq Capital Market, including, in the case of all of the members of our audit committee, the independence requirements contemplated by Rule 10A-3 under the Exchange Act. In making such determination, the board of directors considered the relationships that each director has with our company and all other facts and circumstances that the board of directors deemed relevant in determining director independence, including the beneficial ownership of our capital stock by each director.

Audit Committee. Our audit committee is comprised of John Hamilton, Robert Coughlin and Craig Gibbs. Our board of directors has determined that John Hamilton is an audit committee financial expert, as defined by the rules of the SEC, and satisfies the financial sophistication requirements of applicable rules of The Nasdaq Capital Market.

· review with the independent auditors and financial accounting personnel, the adequacy and effectiveness of our accounting and financial controls;

· review the financial statements contained in the annual report and quarterly report to shareholders with management and the independent auditors;

A copy of the code is posted on our website, www.aridispharma.com. In addition, we post on our website all disclosures that are required by law or the Nasdaq rules concerning any amendments to, or waivers from, any provision of the code.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our directors, executive officers and beneficial owners of more than 10% of our common stock to file reports of holdings and transactions in our common stock and our other securities with the SEC. Officers, directors and beneficial owners of more than 10% of our common stock are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file. Our directors, executive officers and beneficial owners of more than 10% of our common stock did not become subject to such Section 16(a) reporting requirements until August 15, 2018. To our knowledge, based solely on our review of Forms 3, 4 and 5, and any amendments thereto, furnished to us or written representations that no Form 5 was required, we believe that during the year ended December 31, 2018, all filing requirements applicable to our executive officers and directors under the Exchange Act were met in a timely manner except that a Form 4 was filed late in December 2018 for stock options granted to each of Fred Kurland and Wolfgang Dummer.

We entered into a Joint Venture Contract, as amended, effective August 6, 2018, or the JV Agreement, with Shenzhen Hepalink Pharmaceutical Group Co., Ltd., a People’s Republic of China company, or Hepalink, a related party and significant shareholder in the Company, pursuant to which we formed a Joint Venture company named Shenzen Arimab BioPharmaceuticals Co., Ltd., or SABC, a People’s Republic of China Company, to develop, manufacture, import and distribute AR-101, AR-301 and AR-105 in China, Hong Kong, Macau and Taiwan, collectively, referred to as the Territory. The Joint Venture received regulatory approval in China and SABC was formed on July 2, 2018.

Hepalink is obligated to contribute the equivalent of $7.2 million in renminbi, the official currency of the People’s Republic of China, and owns 51% of the capital of SABC and we are required to contribute (i) $1.0 million in cash and (ii) a license to AR-101, AR-301 and AR-105 pursuant to an Amended and Restated Technology License and Collaboration Agreement between us and SABC and we own 49% of the capital of SABC. In addition, Hepalink will provide SABC with clinical and regulatory personnel services for clinical and regulatory review, application and filing procedures in the Territory and we will provide clinical and regulatory personnel services to assist in coordination of the execution of the clinical study in China and also with CMC personnel services for drug supply and manufacturing planning Hepalink is obligated to make an additional equity investment of $10.8 million into SABC in connection with a future financing of SABC provided that (i) such financing does not occur earlier than January 1, 2019, (ii) top-line clinical results of the first global AR-301 phase III study are available, (iii) CFDA approval for a phase III clinical trial in China is granted, (iv) we have not breached the Amended and Restated Technology License and Collaboration Agreement and (v) the SABC Board has approved such financing.
